so, i bought a new powercolor graphic card r7 250x it was working fine for 20 days or so then one day my didn't show any display. i thought maybe the monitor power cable was loose but NO...everything was working fine except the card ...i opened my Cabinet to check.....the card fan was spinning but there was no display i unplugged the gpu and connected the display to mobo. it was working fine cant seem to get the hang of the problem.
